Do you know what is the difference between HDD vs SSD? Which of these two is better? If you do not know the answer to all these questions, then there is nothing to worry because today I am going to explain to you people about SSD vs HDD in detail so that no doubt remains in your mind.
Whenever someone thinks of getting a new computer system, there is always a concern in the mind of many that it would be appropriate for them to take which storage drive for the storage of their computer. And they have only two options to choose from, one is Solid State Drive (SSD) and the other is Hard Disk Drive (HDD). But due to lack of correct information, they do not get this decision and even if someone takes it, they fall in loss due to lack of information.
There is no easy or simple answer here that which of these two is better and which one will be right for you. Because the needs of all people are different, so they have to decide which one will be right for them.
Along with the need, you will also have to look at your preference, and also your budget. Keeping all these things in mind, you can buy a right hard drive for your computer.
So today I thought that why not give complete information about these hard drives to you people so that you can decide for yourself which one will be right for you according to your need. Then without delay, let’s know which is better in HDD vs SSD in Hindi, you will know full information about all these in this article today.

What is HDD (Hard Disk Drive)
The full form of HDD is Hard Disk Drive. HDDs were first introduced in 1956 by IBM. You might be surprised by this people but it is true that this technology is 60 years old. Magnetism is used in an HDD to store data.
A read/write head floats above the spinning platter to write the data and to read the data. The sooner this rotating platter rotates, the sooner the HDD can perform. In today’s world, a typical laptop drive spins at 5400 RPM (Revolutions per minute) or 7200 RPM, while some spin up to 15,000 RPM.
One of the biggest advantages of using HDD is that you can keep a lot of data in it at a very low cost. Nowadays, 1 TB storage is very common, and gradually its number is increasing day by day. Due to being cheaper than SSD, HDD has become the first choice of people today. Because if compared, SSD is 3 to 4 times more expensive than HDD.
If we talk about the appearance of HDD then from outside it looks exactly like SSD. SATA is used in HDD. Laptop hard drives have a common size of 2.5” form factor while desktop hard drives have a slightly larger size of about 3.5” form factor.
The higher the size of the platter, the more will be the storage capacity. Some desktop hard drives can store up to 6TB of data.
What is SSD (Solid State Drive)
If you do not know about SSD, then let me tell you that the full form of SSD is Solid State Drive. This is also a memory device like pen drive, only it has a little more space and it is a bit more sophisticated device.
Like the memory stick, it does not have any moving parts. Here the data is stored and kept in the micro chip. Where in a hard disk, with the help of a mechanical arm which has a read/write head, the information is read from the correct location to the storage platter.
This difference makes SSD much faster. For example, if I say that if you want to bring a book from one room, then for this you have to search around the room first and then bring it when you find it. On the other hand, if the book is already in front of you and you bring it quickly when asked, how will you feel. Only such SSD works, for which it is much faster than HDD.
NAND-based flash memory is used in SSD. This is a non-volatile memory. Now non-volatile means that whenever you turn off the disk, it will not forget what is stored in it. Meaning there is no memory loss in it. Yes, this is definitely a very big and essential feature of a permanent memory.
When the first SSD first came in the market for the first time, then people did not have much faith in it. But now this technology is being used by people with great enthusiasm. And in this, SSD has more longevity than HDD.
An SSD does not have a mechanical arm, so an embedded processor (or brain) also called a controller is used to read and write data, with the help of which many tasks such as reading and writing of data are done. Is.
Controller is used to know the speed of SSD. Whatever decision it takes to store, retrieve, cache and clean up the data, all these things determine the overall speed of the drive.
I would like to say one thing here that a good controller is the real hallmark of a good SSD. You must be wondering right now how this SSD would look like. So let me tell you that its technology is kept encased in a plastic or metal case. It looks like a battery.
The form factor of SSD is similar to that of a regular hard drive. Its standard sizes are something like 1.8”, 2.5”, and 3.5” size which easily fit into the housing and connectors like its similar sized hard drive.
For their standard size, SATA is used according to the connector. Apart from this, there are other SATAs as well such as mini-SATA which are smaller in size that is why they are also called mini-SATA (mSATA) and it can be easily installed in the mini-PCI Express slot which is used in laptops. Goes.
